Thus the wavelength of a 100 MHz electromagnetic (radio) wave is about: 3Ã10 8 m/s divided by 10 8 Hz = 3 metres. The wavelength of visible light ranges from deep red, roughly 700 nm, to violet, roughly 400 nm (for other examples, see electromagnetic spectrum).
Mumble, Putting a modem to bridge mode just makes it dumb, it will let anything pass though, though when hits the Router it will then get routed to where needs be. The option is really up to yourself. Once advantage would be, only the Router will need to be setup accordingly, as the modem just passes internet traffic.
To put it simply, a Client Bridge links computers while a Wireless Repeater connects routers. These mode changing options can be found in later builds of DD-WRT under the (as seen in the image above). The default mode in DD-WRT is AP, which sets your router up as a standard access point for users. A Client Bridge can connect disparate pieces of a company of home network that were previously unable to connect through a router.
